Abstract
Faraday's Experiments on Self-induction In 1834, a young man, Mr. William Jenkin, brought to Faraday's notice a new effect of electro-magnetic induction. The shock obtained on breaking contact with a voltaic battery was greatly enhanced if a coil instead of a straight wire was used as the conducting circuit. On October 15, 1834, Faraday began experi ments on this action of the ‘extra current’, as he called it, and traced it to induction between the neighbouring turns of the coil at the moment of disjunction. “These effects,” he wrote in his Diary a month later, “show that every part of an electric current is acting by induction on the neighbouring parts of the same current, even in the same wire and the same part of the wire.”
